SAFETY HOLDER FOR TANK WAGON RECEPTACLES Filed Oct. 7, 1956 Zhmentor disfiiz JffPaa A Patented May 17, 1938 UNITED STATES PATENT 'OFFICE SAFETY HOLDER FOR TANK WAGON RECEPTACLES Application October 7, 1936, Serial No. 104,498

3 Claims.

This invention relates to safety holders for tank truck receptacles and the like, and while designed more especially for holding those oil and gasoline receptacles usually disposed within a box 6 at the rear end of the truck and quickly available upon opening the doors of the box, may be employed at other points and for holding other characters of merchandise.

The object of the invention is to provide a holder for one or more merchandise receptacles which will maintain the receptacle or receptacles against accidental shifting of position regardless of the roughness of the roadway traversed by the truck. Fixed, but readily removable and replaceable, receptacles have the following advantages. They avoid chance of explosion due to the pro duction of a spark following forceful contact between the receptacles or between a receptacle and a. metal part or object within the box; they insure the preservation of relatively noiseless travel as regards the rear end truck equipment accessories; and they avoid the production of dents in the receptacles and the consequently shortening of the life thereof and a less that 100% measme delivered to the consumers depending on the receptacle as a standard of predetermined capacity.

Another object is to provide a holder for accessories of the spring-clamp type which can be withdrawn enough by hand from the accessory to permit the latter to be easily lifted out of the box or returned thereto, or whereby the accessory can be tilted to serve as a lever to repress the clamp for the easy removal or replacement of the former, and this method for the removal or replacement is peculiarly desirable for the clamp for holding a single receptacle or a funnel. v

With the objects mentioned in view the invention consists in certain novel and useful features of construction and combination of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:-

Figure 1 is a top plan View of a receptacle box of the type commonly found at the rear end of tank trucks, the top of the box being omitted.

Figure 2 is a view with the rear end of the box and equipment in the foreground omitted to disclose the single clamp equipment in side elevation.

v In the said drawing, I indicates a box or housing commonly provided at the tail end of an oil or gasoline tank truck, access to the box. being controlled by doors 2 forming the rear wall of the box.

The box is employed to hold receptacles for a few gallons of oil, gasoline or the like for retail sale, a funnel for convenience of delivery from such receptacles, and sometimes tools or other equipment.

With the single yoke clamp, preferably used for funnel securing purposes, although it may also be used for receptacles, n0 handle is necessary, as the funnel or receptacle is light and of sufficient stiffness to be tilted to repress the clamp in both the removal and replacement operations as indicated by dotted lines in Figure 2.

This single-type of yoke clamp is preferably in the form of a rod bent to provide an arcuate arm M and rebent to provide a pair of rearwardlyprojecting ends 15, which arms respectively extend slidingly through U-brackets I6 bolted to the bottom of the box as at IT. Springs I8 upon the arms bear against the rear arms of the brackets l6 and collars 19 upon the latter, and said arms also have collars 20 to abut the rear faces of the inner or front arms of the brackets and thereby limit the force of compression of the arm I4 on. the funnel, which arm I4 may be equipped, as shown, with a tubular sound-deadening cushion 2| for direct contact with the funnel.

From the foregoing, it will be apparent that I have produced a construction which embodies the features of advantage set forth as desirable, and it is to be understood that while I have described and illustrated the preferred embodiment, I reserve the right to all changes within the spirit of the invention and Without the ambit of the prior art.

I claim:

1. A bucket clamp comprising a segmental yoke having its opposite ends terminating in a pair of parallel members extending perpendicular to the yoke, a pair of U-shaped brackets having openings in their ends, each of said brackets respectively slidingly receiving one end of the segmental yoke, abutment collars on said parallel sliding yoke ends located between the spaced apart ends of the brackets, and springs inserted between said abutments and one end of the brackets to urge the yoke in one direction, the abutments being adapted to limit the sliding movement of the yoke under the expansion of the springs by contacting the ends of the brackets opposite those with which the springs contact.

2. The combination with a motor truck box for the reception of cylindrical containers, of a clamp for yieldingly holding the container against a Wall of the box, comprising an arcuate yoke for snugly embracing a container at the opposite side thereof from the wall abutted by the container, arms extending from the ends of the yoke in a direction away from and perpendicular to said wall, brackets secured upon the bottom of the box for and each slidingly receiving one of said arms, and springs fitting on said arms and applying pressure thereon and on said brackets for causing the yoke to clamp the container against the abutted wall of the box.

3. A clamp for engaging the curved wall of a cylindrical object, comprising a rod formed with an arcuate yoke portion and rebent at the ends of the latter to provide a pair of parallel arms projecting in the opposite direction to that faced by the concave face of the yoke, a pair of U-shaped brackets, each slidingly receiving one of said arms at spaced points, fixed collars on said arms between said spaced points, springs on the arms and engaging the respective brackets and collars and tending to force the yoke in the direction faced by its concave side, and means to limit the movement of the yoke in the direction mentioned. 10
